حلقات O من Viton FKM بقطر داخلي 0.549" وقطر مقطع 0.103" | AS568-113 | داش 113 | متوافقة مع FDA | صلابة 60 | أبيض (100/عبوة)

Replaced the black Buna-N rings in my food-grade pump with these white Viton ones; the 60 durometer feels noticeably more pliable, and they’ve held up fine under steam cleaning cycles so far.

These white o-rings fit perfectly in my espresso machine steam wand, which sees constant 300°F+ temperatures. The 60 durometer is soft enough for a good seal but hasn't deformed at all after weeks of use.

I’ve swapped these into a few high-heat fittings that killed my old Buna-N rings within weeks, and the -15°F to +400°F range covers everything I throw at them. The white color makes them easy to spot against darker housings too.
